-> bool
- collection IEnumerable
- The collection to set the item in.
- index Int32
- The zero-based index at which item should be set.
- item Object
- The item to be set.
- checkReadOnlyAndBounds Boolean (Optional)
- to return if the collection is read-only or the index is invalid; to attempt setting the element without checking the read-only state and bounds. This parameter is optional.
Default value: . - throwError Boolean (Optional)
- to forward any exception thrown by a found setting member; to suppress the exceptions thrown by the found setting member and return on failure. This parameter is optional.
Default value: .
Boolean if a setting member could be successfully called;
if such member was not found, or
checkReadOnlyAndBounds is
and the collection was read-only,
or
throwError is
and the setting member threw an exception.In Visual Basic and C#, you can call this method as an instance method on any object of type
IEnumerable. When you use instance method syntax to call this method, omit the first parameter. For more information, see
Extension Methods (Visual Basic) or
Extension Methods (C# Programming Guide).
The item can be set in the collection if that is either an IList or IListT implementation.
If it is known that the collection implements only the supported generic
IListT interface, then for better performance use the generic
TrySetElementAt<T> overload if possible.
This method returns also for multidimensional arrays.
